The ISL81805EVAL4Z dual-phase negative-to-positive voltage conversion evaluation board features the ISL81805, which is an 80V high voltage, dual synchronous boost controller that offers external soft-start and independent enable functions and integrates UV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 1MHz helps optimize the inductor size as the strong gate driver delivers up to 20A for the total output.
